Japanese Shiny Treasure ex (SV4a): prices, chase cards and box guide

The short version

Shiny Treasure ex (SV4a) is the Japanese High Class Pack behind English Paldean Fates, and on price it is a three card set. As of mid-September 2026, Mew ex #347 at about $515, Charizard ex #349 at about $226 and Gardevoir ex #348 at about $152 hold about 55 percent of the $1,624 it costs to buy one of every entry on the set page. Of 12 cards we could match to an English twin, 11 cost less in Japanese.

A sealed box is about $137 for 10 packs of 10 cards, and a loose pack about $13. Each pack guarantees one Pokémon ex and nothing else. This site computes no expected value for Japanese product and has no Japanese pull-rate data, so a box is entertainment. To get a specific card, buy it, and check its number first: the same name sits on cards at very different prices.

What Shiny Treasure ex is

The official product page gives a release date of December 1, 2023, a price of 550 yen per pack with tax, 10 cards per pack (a standard Japanese pack usually holds 5) and one Pokémon ex guaranteed in every pack. PokeBeach reported 10 packs to a box, which is 5,500 yen at retail.

PokeBeach describes it as Japan's annual reprint set: a 190 card main set, mostly reprints with only 17 brand new cards, plus 170 secret rares. Every regular Pokémon in the main set also appears as a Shiny card, except Gimmighoul and Gholdengo. Bulbapedia puts the total at 360 cards, the largest Japanese set up to that point.

A key to the letters: S is a Shiny Rare, the small Shiny Pokémon collectors call baby shinies. SSR is a Shiny Pokémon ex, labelled Shiny Secret Rare here, as TCGplayer lists it. AR and SAR are the English Illustration Rare and Special Illustration Rare, and UR is the gold card.

This site shows 484 entries because TCGplayer lists Mirror Holofoil parallels separately, with names in English. 293 entries carry no rarity label, including Iono #350, which PokeBeach lists among the Special Art Rares, so that group shows seven cards here, not eight.

The English counterpart is Paldean Fates, released eight weeks later on January 26, 2024, and the match is partial. Bulbapedia says Paldean Fates combines Shiny Treasure ex cards with leftovers from Raging Surf, the Terastal Starter Sets, Ancient Roar and Future Flash. The English set is 245 cards with a main set of 91, against 360 and 190 in Japanese.

The numbers

The block below shows the set's live figures. Its count includes the Mirror Holofoil entries, so it is higher than the official 360.

The median entry is worth 49 cents. Only 17 cards clear $10 and 3 clear $50.

The seven cards labelled Special Art Rare average about $134 and total about $940. Add Iono #350 at about $34 and the eight come to about $974, roughly 60 percent of the set. The three Pokémon ex are about $893 of that, and the five Trainers cost about $81 between them.

The cards the set is named for are cheap. The 129 Shiny Rares average about $3.06, so all of them together cost about $395, less than one Mew ex #347. The 18 Shiny Pokémon ex average about $3.04, and the four Art Rares about $6.71.

Rarity and price do not line up. PokeBeach lists six gold cards; the four labelled Ultra Rare here average about $5.33, and the five full art Trainers labelled Super Rare average 59 cents, less than many baby shinies. The 24 regular Pokémon ex, the Double Rares, average 45 cents, led by Charizard ex #115 at about $2.57.

Chase cards

Here are the set's eight most valuable cards today.

Mew ex #347 at about $515 is worth more than Charizard ex #349 and Gardevoir ex #348 combined, about $378, and is close to a third of the set's value. Fourth is a Shiny Rare, Pikachu #236 at about $45, then Iono #350 at about $34 and Clive #352 at about $21. Five of the next nine are also baby shinies: Mimikyu #265 (about $20), Ditto #309 and Snorlax #310 (about $19 each), Maushold #318 (about $18) and Tandemaus #317 (about $16).

That list hides a trap. Charizard ex appears as #115 at about $2.57, the Shiny #331 at about $14 and the Special Art Rare #349 at about $226, and Mew ex as the Shiny #327 at about $19 and #347 at about $515. A title that says only "Charizard ex Shiny Treasure Japanese" could be any of them, so read the number in the photo before the price.

Japanese versus English prices

Both figures in each line are US TCGplayer market prices as of mid-September 2026, rounded to the dollar, and neither is a price in Japan. Each Japanese card is paired with the Paldean Fates card of the same name and rarity role.

• Mew ex, Special Art Rare: $515 Japanese, $872 English (#232).
• Charizard ex, Special Art Rare: $226 against $277.
• Gardevoir ex, Special Art Rare: $152 against $173.
• Iono, Special Art Rare: $34 against $26.
• Clive, Special Art Rare: $21 against $23.
• Pikachu, Shiny Rare: $45 against $78.
• Mimikyu, Shiny Rare: $20 against $51.
• Snorlax, Shiny Rare: $19 against $51.
• Ditto, Shiny Rare: $19 against $38.
• Maushold, Shiny Rare: $18 against $31.
• Tandemaus, Shiny Rare: $16 against $30.
• Mew ex, Shiny Pokémon ex: $19 against $33.

Eleven of the 12 are cheaper in Japanese, and Iono is the exception. The biggest gap in dollars is Mew ex, about $357. The top three together cost about $893 in Japanese and about $1,322 in English. The baby shinies show the widest gaps in proportion: the six matched here sell for roughly 37 to 60 percent of the English price. Those pairs are not physically identical either: PokeBeach noted at release that the Japanese baby shinies have no holo border, unlike the English ones.

The Shiny Charizard ex #331 and the Art Rare Mimikyu #341 are left out because we could not match them with certainty in our Paldean Fates data. A price gap between languages is a fact about two markets, not a recommendation. A Japanese card is not legal at US Championship Series events, so in the US it sells mostly to collectors, as our Japanese versus English guide explains.

Sealed product

The Shiny Treasure ex booster box is about $137 at market (TCGplayer low about $119) and a loose booster pack about $13.36. With 10 packs in a box, that is about $13.70 a pack, and ten loose packs would cost about $134, so the sealed box carries almost no premium, about $3.

English Paldean Fates never had a booster box, and a loose Paldean Fates pack is about $25. Both are 10 card packs, but the contents differ, so neither prices nor rates carry over. The site's measured English rate for a Special Illustration Rare, about 1 in 62.5 packs, and the English EV on the sealed EV board say nothing about the Japanese pack.

The official guarantee is one Pokémon ex per pack. PokeBeach reported on a box opened by the official Japanese Pokémon card channel before release: one Art Rare, two Shiny Rares and one Shiny Pokémon ex, and no SAR, SR or gold UR, so it concluded those three tiers are not guaranteed in a box. That is one box, not a rate. PokeBeach also confirmed that "god packs" exist, with no figure for how often they appear.

Missing shrink wrap is not a warning sign by itself. According to a March 2025 Screen Rant report, Pokémon Center stores in Japan take the plastic off booster boxes at sale. That leaves no outer seal to judge, so weigh the seller's record. As an importers' rule of thumb, look for an unbroken cardboard tear strip. Our resealed product guide goes further.

How to buy it

Every Shiny Treasure ex card and product page gives the US TCGplayer market price for that printing, a price history that starts on September 18, 2026, the price 12 percent below market, and two eBay buttons. Button one searches eBay for Buy It Now listings from US sellers with Japanese, JPN or JP in the title, excludes proxies, lots and other languages, sorts by price plus shipping, and caps the item price at 12 percent under market. Button two removes the cap. Both are affiliate links. The block below runs those searches for the SV4a booster box and booster pack, capped under the below-market price.

Shipping sits outside the cap, so add it yourself. A listing is below market only when the landed price, item plus shipping, comes in 12 percent or more under, which for the box is about $121 delivered. A seller's "was $X" discount counts for nothing. An empty capped search means nothing is listed below market at that moment: use button two to see every current price, and eBay's "Save this search" so eBay emails you new matches.

Both buttons are limited to US sellers, so nothing is imported. Order from Japan instead and, since August 29, 2025, a shipment of any value can pick up import charges, so look for that line at eBay checkout.

Site card prices are for raw Near Mint copies. Under the methodology a Lightly Played copy is measured against 85 percent of market, so a Lightly Played Mew ex #347 has to land near $385, against about $453 for Near Mint. eBay's Authenticity Guarantee covers trading cards sold for $200 or more in the US. Mew ex #347 qualifies even at those prices. Charizard ex #349 qualifies at market, but a copy at its below-market price of about $199 would not.

Before paying, match the number in the photos (347/190 for the Mew ex) and compare the back with another Japanese card, not an English one. The fake card guide lists the other checks.

Who it suits

Collectors who want the Mew ex, Charizard ex or Gardevoir ex artwork and do not need a tournament legal copy. All three cost less in Japanese today, the Mew ex by about $357.

People who like opening packs. A Japanese pack is about $13 against about $25 for a loose English pack with different contents. Budget the $137 box as entertainment, because we have no measured Japanese rates and cannot say what a box returns.

It does not suit players, who need English cards for sanctioned US events, or anyone hoping a box pays for itself: more than half of the set's value sits in three cards that no box is guaranteed to hold.

Bottom line

Shiny Treasure ex is a 360 card Japanese reprint set whose value is concentrated in three Special Art Rares. As of mid-September 2026 Mew ex #347 is about $515, a sealed 10 pack box about $137 and a loose pack about $13. Eleven of 12 matched cards cost less than their Paldean Fates twins. Only a Pokémon ex per pack is guaranteed, and this site publishes no EV for the box. Pick your card from the set page or the Japanese index, confirm its number, use the eBay buttons there, add shipping and any import charges, and compare with the Japanese price, never the English one.
